Radius: Securing Public Access to Private Resources

I read a lot of books, some of them are inspiring, entertaining and
relevant. Some are dull, overly terse and yet still useful; The O’Reilly Radius book is more akin to
bad dental surgery.

What really annoys me is that I can’t think of a better way of
presenting such as dry topic, the book provides detailed coverage that
is just as easy to read and understand (and as fascinating) as the
original RFC version. It
then introduces the basic uses of FreeRadius.

If you need to learn about RADIUS I’d suggest the RFCs and the man pages that come with your server
instead of this title; and spend the saved money on caffeine, you may well
need it!
